[Rosegarden-user] Re: Your virmidi howto

[Larry T. <lt...@we...>]

Hello again, Frank, and thank you very much! This answers a lot of questions.
I hope you don't mind that I'm copying this reply to the Rosegarden-Users 
list, where I initally brought up the problem.

That's great! I haven't had time to try this yet, but that's good news.

The only reason I was trying this was as a basic test of virmidi and aconnect 
- to narrow the problem down so to speak.  The only purpose of this 
configuration was for seeing if the basic virmidi/aconnect stuff works. 

Apparently, it does not, in this case. But because of what you wrote above, it 
doesn't matter that this doesn't work, for the time being (because aconnect 
is not needed).

Thanks again for your help!
